Visit of the Valley of Fire this week-end. Located in Nevada, about one hour North-East of Las Vegas, not as famous as the National Parks nearby (Zion, Grand Canyon, etc...), it is only a state park, but it is well worth the visit.

Named because of the rock vibrant red colors that makes them look as if they were on fire. 150 millions year of erosion beautifully shaped the rocks, you can find many arches there. A lot of spectacular vistas in the park as usual in this part of the USA.
